General Cultivation Q&A

How much head space do the plants need? How tall will they grow? Will they grow depending on how much space they have? Will height affect yield? At present, I have space with about 45cm vertical clearance.

How do I find out what size and speed the fans will need to be for my closet? The closet will be approximately 1.8m Long by 2m High by 1m wide, any other info needed before you's can tell me how to find that information out? Cheers Andrew

What kind of pH tester will I need there are some many out there to choose from I am starting to get confused with all the different brands is there any real difference? or is just the usual meaning that you pay for the brand? So any help would be helpfull Cheers Andrew

Hi all, I'm just about ready to harvest and want to try the 48 hour dark trick. I'm using an airo system with pumps running 24/7, I have a beautiful VB at day 54 of flower, I hope she turns out ok as she is full of seed, More seed than i've ever seen. Should i keep the watering up?, Or should i give her less or stop completely?. I hope i've got the harvest time right, I've been flushing for 2 weeks and she still looks verry healthy, Alive and green as though i'm feeding her N. Any help much appreciated, Thanks heaps, Paranoid.

Hi all. I am again pushed for grow space, a never ending problem it seems, and one we probably all share. Tigger sure seems to have this problem . So I thought about the best way to condense the plants of a new batch of seed, I want to grow to select a mother. It's White Widow x Sweetooth. I bought a slab of rockwool from the hydro shop for $11.00. I sliced some cubes off the rockwool, and made drills in them, so to germinate the seeds. At the same time as cutting out the 1 inch cubes, I also made my own larger cubes similar to the hydro shop jobies that sell for for $1.20 or more each. You get far more than eleven out of a slab of rockwool. While I was waiting …

I'm starting this thread basically just as a grow diary for my second grow. Since the first grow (ak47 & white widow), I have made quite a few changes, first time round I had big problems with heat in the box, so I decided to use a small air conditioning unit, which I soon realised was doing very little for the power/space it was using, this time round I traded the a/c unit in for an air cooled hood for which I have installed ducting that goes into my roof, much more effective and economic! (I like)... For the grow I have 3 clones all swt#3 (I origanally had 4 swt#3, and 2 headstone from SPC, but seeing as I didnt have the room the rest have gone into a mates grow …

I'm planning on setting up a small grow in my wardrobe on a shoe-string budget. I need someone to give me some advice on whether the following idea is a good one or not. - Two chambers. Bottom one used for growing, top for drying. The bottom chamber is 40cm high, 40cm wide and 45cm deep. The top is 35X40X45. - Plants will grow in rockwool, using X-Factor or similar nutrients. - CO2 provided by vinegar/bi-carb drip. - Flourescent lighting. - Holes to be cut in rear of both chambers (about the size of a 50c piece) for ventilation. I'll be growing White Widow X Sweet Tooth. It will only really be for myself and a small circle of friends, essentially because we're…

These are some pics from my first grow (400WHPS, Organic), the plants are SWT#3 ( from stonedas) thanks mate , Blueberry, and Northern Lights. The pics where taken yesterday and i think i will be harvesting the NL and SWT#3 in a couple of days, the Blueberry was slow to flower and has another week or 2 to go i reckon. Ill try and get some pics of the finished product in a few weeks. I have also put a few pics of my outdoor Very Berrys, thought you might like to see what they are like outdoors. Sorry about the crappy pics , the camera was a bit old. Also a big thanks to stonedas, rob and some other people off OG for helping me out along the way and giving me ad…

Chlorine overdose causes leaf margins and tip burn and leaves to turn bronze. Repeated applications of chlorine also acidify soil. Remove chlorine from water by letting it sit overnight in an open reservoir or barrel. When in contact with air, it volatizes into a gas and dissipates into the atmosphere.
